Problem #1: Galaxy S5 “Unfortunately App has failed” error

Because of terrible luck, I had new Samsung 3 phones stolen in a year. I bought used Samsung S5 from a guy on Craigslist. I confirmed the phone was legit and not stolen. (He’s a respected local business owner). He sold the phone because after the Lollipop upgrade he was getting numerous “Unfortunately App has failed” messages so he upgraded to an S6 and sold me his used S5.

I’ve done a factory data reset numerous times and the problem with Unfortunately App has failed” (this is for dozens and dozens of Apps) immediately returns. The phone on occasion will shut-off and restart for no apparent reason.

I found a guy that specializes in Samsung rooting software. He did a complete reinstall of the correct T-Mobile Lollipop 5.1.1 software and the problems continued to occur as soon as the phone was restarted. He tried many different software versions. Out of frustration he installed a root program Maverick 5.1.1 V9.7

The phone worked normally without all of the Unfortunately the App error messages for one week. I swapped batteries. When I restarted the phone the error messages start happening again. They only occur randomly and sometimes the messages popup fast than you can click OK. I only have a couple of downloaded apps, I deleted them and the problem still exists.

Do you think it could be a hardware issue or that some phones are not fully compatible with the Lollipop upgrade?

Thanks for your help. I’ve spent a ridiculous amount of time trying to fix this problem. — Joe

Solution: Hi Joe. Based on your description above, it looks like you have done everything in your power to try to fix this issue. Frankly, we have no way of knowing for sure where the problem is coming from but since you have already  performed a wide range of software remedies and troubleshooting, it can be safely assumed that a hardware malfunction may be the trigger.

Problem #2: Remedy for Galaxy S5 random restart issue

Phone was restarting on its own and getting worse. The same as many writing in on your forum. How did I cure mine? A piece of paper towel.

Try this first before you go through all the cache clearing, the heartbreak of factory resets and trips to the revered Olympus for confused consumers aka the  Samsung kiosk at Best Buy. S5s have a loose fitting battery.

  1. Tap hard around on your phone case. Bend it a bit without any harmful force. If it shuts off or restarts you have the likely suspect. A loose fitting battery.
  2. Remove the battery and clean all terminals. Take a small piece of paper doubled paper towel and wedge it in the negative end of the battery as …just enough to stabilize it tightly against the positive contacts. A tiny piece of paper towel does it. Don’t obstruct closing the back of the case.
  3. Close it up and tap around on your phone again. Problem gone?

(Big DUH.) The KIS solution just saved you a lot of worry.

 I’ll skip the obvious joke of this being an absorbing solution. Too late.  — George

Solution: Hi George. Thank you for sharing your experience and solution for random restart problem. We usually assume that the battery connectors are okay when we give instructions for a fix and your experience is a good reminder for us to include it in our future posts. Again, we appreciate your effort and time in letting us and the entire Android community know of an effective way to counter this issue.

Problem #3: Battery drain issue on brand new Galaxy S5

I bought Galaxy S5 yesterday. The issue is that its battery is draining fast. I have done everything so far, installed black wall paper, got rid of extra apps that i installed, made a lot of changes in system to save battery, installed Battery Doctor. It seems a bit better than yesterday . But still battery drained from 100 percent to 52 percent in 12 hours. My brother has same S5 he got it a year ago and he says his battery used to run 2 days easily when he bought it. I was a bit worried as I purchased it from non-UK based online site and it came with EU charger. I am using my previous Galaxy S3 Mini charging socket. There is no problem in charging but draining is faster than I expected.

My bro got his S5 from UK . I have changed my cell to safe mode to see how fast battery drains. Could it be the charger? Or have I been sold faulty phone? — Hadeel

Solution: Hi Hadeel. The best thing that you can do to isolate the real problem further (since you seem to have done the required software troubleshooting for this issue), is by buying an original Galaxy S5 battery so you can compare the performance. If the rest of phone functions work as expected, the problem may actually be on the battery only. Storage conditions of the device before it was sold can sometimes affect the battery. While the chance of having a defective battery in a brand new Galaxy S5 is slim considering the total number of worldwide sales, we can’t really totally eliminate it either. We know that telling you to buy another battery may sound too much but there’s no other practical means to measure battery performance in your situation.

Problem #4: Galaxy S5 losing battery power fast

Had this phone for 3 months. Phone charged fine during the first week with factory charger, then would only charge with phone off (USB 3.0). IF I used the phone and tried to charge the battery would drain. I contacted T-Mobile and they sent a replacement phone. Same charging problems. I switched to a older 2.0 USB charger same voltage 2.0 and amperage and the phone charges fast. I ordered 2 new Samsung batteries but the USB 3.0 charger still will not charge the battery unless I have the phone off. The other  2.0 charger charges the phone quickly even when using. Despite all this, I have yet to get anywhere near the 9 hour charge usage i.e. on any battery while surfing the internet.  Like Facebook.  And it’s more like 2 or 3 hours of usage. I try to shut off all background apps and turn down the display brightness, turn off Wi-Fi, but still. I had to use Energy saving mode for a while until I got my new phone from T-Mobile. I tried resetting the phone.

Why won’t my phone charge  normally and hold a charge longer using the USB 3.0 cord? I switched cords but still same problem. Any help would be great.  Thanks. — Chuck

Solution: Hi Chuck. USB 3.0 is just one of USB specifications in use today but it doesn’t matter much during the charging process if you pair it with a slower wall wart. Make sure that the USB 3.0 cable you have is connected to a charger block that uses Qualcomm’s Quick Charge 2.0 , or Samsung’s Adaptive Fast Charging technology so it charges faster. Better still, use only the original Samsung Fast Charging Wall Charger.

Samsung devices won’t fast charge if the screen is on so make sure to either turn off the screen or the phone to optimize it.

If battery drain happens when you are using the phone while charging, that’s an indicator that you have many applications running actively and in the background. It may also mean that the screen’s brightness is set to high. Try to tweak your screen brightness settings and close background apps to minimize battery drain.

If you have a lot of social networking apps, make sure that you set them to manual sync only to prevent the phone from constantly checking for updates from remote servers. This process is one of the most common reasons why a smartphone loses battery power faster than normal. Turning off Wi-Fi and mobile data on your phone while charging is also an effective way to check battery drain.

Problem #5: Galaxy S5 freezes and overheats

My phone constantly freezes and runs hot. This has been happening forever now. Sometimes it’s worse than others. It’s definitely stuff happening in the background. Half of the time when I go to the screen to force quit apps, the culprit is Google Play Music that is on for some reason. When it freezes there are different levels of how bad it gets. Sometimes it takes me a while to type. Other times the apps start crashing 1 by one, or the phone will ring while I’m texting or emailing and it freezes and I can’t answer the call or continue typing. I HATE THIS PHONE. It shouldn’t be like this, right?

Recently I’ve started turning on “restrict background data” when I’m in a Wi-Fi area. That’s the only thing that seems to fix it, but can’t keep it like that all of the time.

What can I do other than buying a new phone? — Sharon

Solution: Hi Sharon. Freezing and overheating in an electronic device are usually symptoms and not problems themselves. Either there’s a software issue or a hardware malfunction as a cause. To isolate the true cause, you can do the basic software troubleshooting first.

How to wipe the cache partition of an S5

A good way to start rolling is by wiping the cache partition. Here’s how to do it:

  • Turn the phone off.
  • Press and hold the following buttons together: Power, Volume Up and Home.
  • Release the buttons once the Android system recovery menu appears.
  • Use the Volume buttons to navigate to Wipe Cache Partition option.
  • Press the Power button to confirm selection.
  • Select Reboot System Now option after deleting the cache. Wait for the phone to reboot.

How to boot your S5 in safe mode

If you suspect that one of your third party apps is the culprit, try restarting your S5 in safe mode for a day to see the difference. Just follow these steps:

  • Turn the device off.
  • Press and hold the Power key.
  • When ‘Samsung Galaxy S5′ appears on the screen, release the Power key.
  • Immediately after releasing the Power key, press and hold the Volume down key.
  • Continue to hold the Volume down key until the device finishes restarting.
  • Safe mode will display in the bottom left corner of the screen.
  • Release the Volume down key when you see Safe Mode.

If you have identified particular apps that seem to be causing the freezing and overheating issues, try to delete their cache and data, or disable them. Better still, simply uninstall them especially if you don’t use them that often.

How to factory reset your S5

Finally, if none of the potential solutions above won’t work, make sure to do a  factory reset.

  • Power down the Galaxy S5.
  • Press and hold the Volume up button, the Home button, and the Power button together until you see the Android on screen.
  • Use Volume down to highlight the wipe data/factory reset option and press the Power button to select it.
  • Use Volume down again to highlight Yes – delete all user data and press Power to select it.
  • Use the Power button to select Reboot system now.
  • When the S5 restarts it should be completely wiped and ready to set up again.

Repair or replacement

Sometimes, software troubleshooting may seem to not do anything at all. In this case, you can assume that there’s a hardware issue at the root of these symptoms. If your phone is still covered by a warranty repair or replacement, make sure to use whatever is applicable.
